Abstract: Embodiments herein relate to in vitro production methods of hematopoietic stem cell (HSC) and hematopoietic stem and progenitor cell (HSPC) that have long-term multilineage hematopoiesis potentials upon in vivo engraftment. The HSC and HSPCs are derived from pluripotent stem cells-derived hemogenic endothelia cells (HE) by non-integrative episomal vectors-based gene transfer.

Abstract: The present invention relates generally to methods for treatment of ribosomal disorders and ribosomopathy, e.g. Diamond Blackfan anemia (DBA). In some embodiments, the invention relates to methods for the use of a small-molecule autophagy modulator for treatment of ribosomal disorders and ribosomopathy. The invention also relates to small molecule drug discovery and methods of screening compositions to determine their effectiveness for treatment of ribosomal disorders and ribosomopathies.

Abstract: Described in the present application are methods for preparing populations of hematopoietic stem cells (HSCs), e.g., autologous and/or allogenic HSCs, using mechanical stretching or Trpv4 agonisists, and methods of use of the HSCs in transplantation. In some embodiments, the methods include providing a population comprising hemogenic endothelial (HE) cells, and (i) contacting the HE cells with an amount of an agonist of transient receptor potential cation channel-subfamily vanilloid member 4 (Trpv4); and/or (ii) subjecting the cells to cyclic 2-dimensional stretching, for a time and under conditions sufficient to stimulating endothelial-to-HSC transition. Also provided herein are methods for treating subjects who have, bone marrow, metabolic, and immune diseases; the methods include administering to the subject a therapeutically effective amount of hematopoietic stem cells (HSCs) obtained by a method described herein.
